"We worked really hard.
"Normally, the bakers get the awards, but now it's the kitchen and shop that have done it."
The six regional winners were selected from 18 finalists by undercover judges.
Every cafe had a signature dish for the competition and 10CC entered sweetcorn fritters with crispy bacon, avocado, tomato and coriander salsa and limed sour cream.
There were 669 eateries at the start of the competition and the finalists, which included The Village Grinder in Kuripuni, were voted on by more than 45,000 cafe-goers.
Head judge and food writer Kerry Tyack says the judges have a tough task ahead, deciding the final winner. "We have done the rounds and I can tell you these six are all very solid representations of what is available in their region."
The national winner will be announced on December 4 and drive away in a Fiat 500S.
Two runners-up will receive $2500 worth of products.
